Question

- A cube has a surface area of 253. square inches. What is the area of one face of the cube in square inches? How do you know?

Answer 1

You have the following information:

Total surface are of a cube = 253 in²

In order to determine what is the surface area of one face, you take into account that a cube has six faces. Then, the surface are of one face is the total surfaces divided by 6, just as follow:

surface area of one face = 253 in²/6 = 42.16 in²

Hence, the surface are of one face is 42.16 in²
